------------------------------------------
Summary: Bulk load mode for LCS
Key: CASSANDRA-11833
URL: https://issues.apache.org/jira/browse/CASSANDRA-11833
Project: Cassandra
Issue Type: Improvement
Components: Compaction
Reporter: Jonathan Ellis
We can currently avoid LCS write amplification on bulk load as follows:
1. Disable automatic compaction
2. Load all the data
3. Force major compaction
4. Re-enable automatic compaction
It would be nice to automate this. E.g. if we detect that L0 contains as much
data as the rest of our arena, skip bubbling sstables up and just major compact
automatically. In a bulk load situation, this would result in exponentially
increasing major compaction sizes -- not as ideal as the manual form with just
a single one, but much better than our current behavior which is not a good
experience for users.
